, Application filed Il'uly 20, 1901, Serial No. 69,005. (No modem To allwhom it may concern.-

Be it known that I, WILLARD GERRALD HARRIS, residing at Oconto, in thecounty of.

Oconto and State of Wisconsin, have invented a new and usefulImprovement in Measuring Devices, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification.

My invention has relation to improvements in measuring devices; and itconsists in the improved construction and combination of parts, ashereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation of thedevice, showing it ad justed for use as a bevel-square or as outsidecalipers. Fig. 2 is a right-hand edge view of Fig. 1. Fig. 3 is a viewshowing the reverse side to that shown in Fig. l and illustrating thedevice adjusted as a try-square. Fig. 4 is a section on the line 4 40fFig. 3, and Fig. 5 is a cross-section on the line 5 5 of Fig. 1.

Referring to the drawings, the letters A and B, respectively, indicatethe two arms of my device, pivoted together attheir upper ends on a bolt0, said bolt having a head D on its outer end. Upon opposite sides ofthe arm A and extending from the side edge inwardly are a series ofscale-marks E E, forming rules on opposite sides of the arm. Theopposite edge of the arm A is provided with a series of shoulders F withscale dimensions indicated thereon in order to form a lumber-gage. Thespace between the several shoulders is indicated by scale measurements,and by fitting the lumber between the upper shoulder and any of thelower shoulders the width of the strip of lumber may be determined.

The upper edge of arm A is provided with a beveled projection G, whichforms a screwdriver, while the lower end of said arm is bifurcated toform the two jaws H H of a wrench. The inner edge of the j aw H ispreferably provided with a series of steps I, so as to make the wrenchsuitable for difierent sizes, and also by having graduated marks tendingprojection K, which forms a calipers= point.

Near its upper end the arm A is provided with an inwardly-extending slotforming a saw-set L. The blade of the saw is inserted in the slot andthe teeth of the saw bent laterally in opposite. directions by anydesired means. The preferable means, however, is to raise the outer endof arm B, so that the inner corner or angle of said arm willbe swungdownwardly, and thereby strike a saw-tooth and bend or deflect saidtooth.

By reference to Figs. 3 and 4 it will be seen that one edge of the arm Aat the upper end of said arm is beveled, as indicated by the letter M.This beveled portion is used as a sawgage for determining whether or notthe saw teeth have been set at the proper angle. After the settingoperation is completed the blade is placed against the non-beveled portion of the arm with the teeth extending over the beveled portion. Ifthe points of the teeth touch the beveled surface, it is thereby knownthat the proper-set has been given to said teeth.

. One edge of arm Bis provided with a series of teeth N, forming akeyhole-saw. For con= venience the opposite edge of said. arm may beprovided-with a scale forming a rule 0, which extends downwardly for adesired dis tance from the upper end of the arm. The remaining portionof this edge of the arm is curved inwardly, as clearly shown in Fig. 1,and beveled on opposite sides to a sharp edge, as shown in Fig. 5, toform a knife P for sharp ening lead-pencils, drc. The lower end of arm Bhas projecting downwardly therefrom a pointed projection Q, forming theother point of the compasses, and from the side edge is another pointedprojection R, forming the other calipers-point.

In Fig. 1 of the drawings I show the arm B adjusted outwardly at anangle, so as to make the device adaptable for use as a bevel-square, andin Fig. 3 I show the arm B adjusted so as to extend at right angles fromarm A, and thereby adapt the device to be used as a trysquare. Thedevice is capable of various otheradjustments. For instance, instead ofhaving the arm B swung out at an angle to the left, as shown in Fig. 1,said arm may be thrown out at an angle to the right, and thereby form amiter-square. When the device is desired to be used as acompa'sses,botharms A and B are swung out at angles and the points J and Q employedas the compassespoints. For use as outside calipers the device isadjusted as shown in Fig. 1, with the arm A also at a slight angle. Thepoints K and R are then brought in contact with the outside surface ofthe device it is desired to secure the dimensions of. For use as insidecalipers the arm B is thrown to the right and the two arms insertedinside of the article of which the dimensions are desired to besecured,with the points K and R against opposite points of the insidesurface of said article.

It will be noticed that the number of inches indicated on the scale Ecorrespond to the number of inches indicated on the scale 0. Now if thearm B is swung to the right so as to be at right angles to arm A itsthen under edge registers with the dotted line shown near the upper endof arm A in Fig. 1 of the drawings, with a scale descending from arm A,the first inch of said scale being delineated on the edge of arm B(indicated by the letter S) and the remaining inches of said scale onthe arm A, and also a scale along the arm B, the figures of the scalesof both arms being an equal distance from the square corner of arm B,and thereby forming a square. It will be evident from the constructionwhichlhave heretofore described that when the square is not in use thesaw-set and screw-driver are left free to accomplish the work desired ofthem.

What I claim as my invention is- A combination-tool, consisting of twoarms pivoted together at corresponding ends, and said arms providedalong their inner edges with scale measurements, the upper portion ofthe scale measurement of one of the arms being devoid of the initialsubdivision or inch of the scale, and the other arm having such initialsubdivision or inch of the scale on its end edge which is at rightangles to the longitudinal edge containing the complete scale, wherebywhen the latter arm is turned at right angles to the other arm, saidinitial .scale subdivision or inch will be brought into registrationwith and complete scale measurement of said other arm, and therebyprovide two complete scales, extending at right angles to each other.

In testimony whereof I aifix my signature in presence of two witnesses.

WILLARD GERRALD HARRIS.
